Window size changed after closed

Firstly, I’m sorry for my bad english.

I just noticed the application window size were always changed every restart. After i checked the BitComet.xml file in the %appdata% , these tags: AppWindowLeft, AppWindowRight, AppWindowTop,  and AppWindowBottom are changed their value right after the program closed. Can you fix these bugs for the next update, please?

I'm using version 1.58, by the way.
